<li>High performance alternative to bounded queues for exchanging data between concurrent threads-用于在并发线程之间交换数据的有界队列的高性能替代方案;</li>
<li>Martin Fowler在自己网站上写了一篇LMAX架构的文章，在文章中他介绍了LMAX是一种新型零售金融交易平台，它能够以很低的延迟产生大量交易。这个系统是建立在JVM平台上，其核心是一个业务逻辑处理器，它能够在一个线程里每秒处理6百万订单。业务逻辑处理器完全是运行在内存中，使用’事件源驱动方式。业务逻辑处理器的核心是Disruptor;</li>
<li>Disruptor它是一个开源的并发框架，并获得2011 Duke’s 程序框架创新奖，能够在无锁的情况下实现网络的Queue并发操作;</li>
<li>Disruptor是一个高性能的异步处理框架，或者可以认为是最快的消息框架（轻量的JMS），也可以认为是一个观察者模式的实现，或者事件监听模式的实现;</li>

<li>目前我们使用disruptor已经更新到了3.x版本，比之前的2.x版本性能更加的优秀，提供更多的API使用方式</li>
<li>可以通过Maven或者下载disruptor-3.3.2.jar来安装Disruptor。只要把对应的jar放在Java classpath就可以了</li>
<li>在使用之前，首先说明disruptor主要功能加以说明，你可以理解为他是一种高效的”生产者-消费者”模型。也就性能远远高于传统的BlockingQueue容器<br><h6 id="理解"><a href="#理解" class="headerlink" title="理解"></a>理解</h6></li>
<li style="list-style: none"><input type="checkbox" checked> 在Disruptor中，我们想实现hello world 需要如下几步骤：<blockquote>
<ul>
<li>第一：建立一个Event类;</li>
<li>第二：建立一个工厂Event类，用于创建Event类实例对象;</li>
<li>第三：需要有一个监听事件类,也就是事件消费者，用于处理数据（Event类）;</li>
<li>第四：事件都会有一个生成事件的源;</li>
<li>第五：我们需要进行测试代码编写。实例化Disruptor实例，配置一系列参数。然后我们对Disruptor实例绑定监听事件类，接受并处理数据;</li>
<li>第六：在Disruptor中，真正存储数据的核心叫做RingBuffer，我们通过Disruptor实例拿到它，然后把数据生产出来，把数据加入到RingBuffer的实例对象中即可;</li>
</ul>
